I have been e- smoking for around three months. I have tried every e -cig and a lot of e -liquids from many suppliers. After all of my experiences with the e-cig I have to say that the Joye 510 is the best atomizer for vapor production and taste. ALTSMOKE SILVER BULLET is the Best device I have purchased. The problem with e-liquid is almost all of it is from China. I wanted e-liquid I felt I can trust that was made in the U.S.A. There are two companies I know of that make e-liquid here in the U.S.A. The first one I tried was Johnsons Creek they give GREAT CUSTOMER SERVICE, but I didn't like the smell or taste of their e-juices. The other U.S.A. made e-liquid is VERMONT VAPOR. VERMONT VAPOR clearly is the BEST e-liquid I have tried. It's COOL MINT and, MENTHOL are the BEST tasting e-liquid I have used to date. Vapor production is great. All the other flavors were good also. And most of their products are VG not PG.
